frontend-design is a skill for Claude Code, Codex from victorzhong0110/skill-evolution. It costs 49 tokens per session (474 once invoked), scanned A, original, MIT.

A frontend-design skill for creating a distinctive visual plan and implementation guidance for a page, dashboard, landing page, or restyle.

In plain words
What is it for?
Use it when planning or building a new web interface. It provides a palette, typography, layout sketch, and subject-specific visual direction.
Why use it?
It prevents generic interface decisions by defining the audience, the screen's main job, visual tokens, layout, and a memorable design element before implementation.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

frontend-design scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Frontend Design

Write a short design plan before any markup. The plan is the deliverable the evolution tasks score; the code comes after the plan is unique to this brief.

1. Pin the subject

Name the product or page, who it is for, and the single job of the screen. If the brief is vague, choose a concrete subject and state the choice. Pull visual vocabulary from that subject's materials, tools, and vernacular — not from a generic "SaaS landing" template.

2. Token sheet (required)

Publish a compact token sheet in the plan:

  • Palette — 4–6 named colors with hex values
  • Type — a display face, a body face, and when needed a utility face for data
  • Layout — one sentence plus a small ASCII wireframe
  • Signature — the one element this page should be remembered by

Derive every later CSS choice from this sheet. Do not invent extra colors in code.

3. Refuse the three defaults

Unless the brief explicitly asks for one of them, do not ship:

  1. Warm cream background + terracotta accent + stock serif display
  2. Near-black canvas + a single acid-green or vermilion accent
  3. Broadsheet columns with hairline rules and zero radius used as decoration

If your first plan matches any of these, revise the palette or signature and say what you changed.

4. Copy is a design material

Interface words name what a person controls, not how the system is built. Buttons say the action (Save changes, not Submit). Errors explain the failure and the next step. Empty states invite an action.

5. Build after the plan

Implement from the token sheet. Keep selector specificity boring. Respect reduced-motion. Spend boldness on the signature; keep the rest quiet.

Files

What ships with it

2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
